Synology DiskStation DS2015xs review

Synology’s DS2015xs makes 10GbE storage networks even more affordable

A mixed performance

We connected the DS2015xs over a direct 10GbE fibre link to an HP ProLiant DL380 Gen9 rack server. This was equipped with dual 14-core E5-2695 v3 Xeons, 64GB of DDR4, an Emulex OCE11102-NM dual port 10GbE adapter and Windows Server 2012 R2 at the helm.

Performance for NAS shares is good with Iometer reporting raw sequential read and write rates of 1077MB/sec and 1002MB/sec Netgear's ReadyNAS 716 mustered speeds of 1032MB/sec and 600MB/sec. The DS2015xs handles backup tasks well with our 22.4GB test folder and its 10,500 small files copied to the share at a speedy average of 265MB/sec.

IP SAN performance over 10GbE is less impressive with Iometer returning read and write rates for a 500GB target of 975MB/sec and 495MB/sec. An MPIO link didn't improve the picture much with read and write speeds increasing marginally to 1161MB/sec and 552MB/sec.

The updated Notes Station lets you create masterpieces on the move and share them with other DSM users
